IMPROVEMENT IN C|STERN -Fl LTERS AND WATER-SEPARATORS.

Specification forming part of Letters Patent No. 169,130, dated October26, 1875; application filed August 2, 1875.

To all whom it may concern:

Be it known that I, WILLIAM B. WILSON, of the county of Jefferson andvState of Kentucky, have invented a Oistern-Filter and Water-Separator,of which the following is a specification:

This invention relates to means hereinafter described, whereby rainwateris collected from the roofs of buildings in a pure and wholesomecondition, and free from such impurities as coal-dust, soot, 860., whichordinarily find their way into the cisterns, and render the water unfitor undesirable for domestic use.

In the accompanying drawing is represented a vertical section of theinvention.

A is a casing, made of some non-corroding metal. It is shaped, as seenfrom the front, about as shown in the drawing, its top being about fourinches square in the clear. The casing is increased in width toward itsbottom, its front and back being parallel with each other. B is a plate,pivoted at a to a partition, 0, and adapted, as hereinafter described,to be moved across the casing. When so moved it assumes the positionindicated by dotted lines. The lower end of the plate B is formed into-acup-shaped receptacle, B,

. the face of which is covered by a gauze-sheet,

b. The cup B is provided-with a descending pipe, 0, leading to a pointcentral of the easing, and also with a small pipe, 0, the office ofwhich pipes is hereinafter explained.

The partition 0 serves to separate the lower portion of the easing intotwo sections, one

, of which terminates in a waste-pipe, d, the

other, 61, leading to the cistern. The lefthand side of the partition 0is provided with a rack having hooks e, to any one of which, as may bedesired, the spring f is attached, the said spring extending to the topof the plate B', to which it is secured, as shown. A pulley, g,.issupported in a stand, 9, extending from the partition 0, over whichpulley passes a cord, h, sustaining a bucket, h, the

other end of the said cord being secured to the lower portion of the cupB. The bucket h is provided with small apertures it" covered with gauzeh.

The operation of the apparatus is as follows: The upper end of thecasing connects with the down spout, which conveys water from the roof.On a brisk shower or rain occurring the main body of the water is leddown the plate B into the waste-pipe d, a portion, however, passingthrough the gauze 1) into the cup B, and thence through the pipe 0 intothe bucket or receiver h. The impurities from the roof are prevented bythe gauze b from entering into the bucket, and are washed from. thegauze into the waste-pipe. Sufficient water having entered the bucket toovercome by its weight the action of the spring f, the plate B is movedso that its top is made to bear against the opposite side of the casing,as shown by the dotted lines. The water is then conducted free fromimpurities into th cistern through the pipe (1.

It will be understood that the spring f and the bucket h are of suchstrength and capacity as to allow of this result when suificient rainmay be supposed to have fallen to wash the roof.

The small pipe 0 at the bottom of the cup B is intended to drain the cupof such small amounts of v water-as may collect therein from dew-falland light showers, which produce too small a quantity of water to effectthe result aforenam ed.

The tension of the spring f may be adjusted by moving the spring fromone of the hooks e to another.

The purpose of the small gauze-covered substantially as and for thepurpose set forth.

' 2. In the casing A, the combination of the pivoted plate B, partition0, having the hooks e, and spring f, substantially as described, and forthe purpose specified.
